To all whom t 71mg/ concern:

Be it known that we, MOSES L. S. BUCK- Nnn and WILLIAM T. BUCKNER,citizens of the United States, residing at Shelbyville, in the countyof' Shelby and State of Kentucky, have invented a new and useful Filter,of which the following is a specification.

This invention relates to filters, and is primarily designed to providean improved device of this character which is particularly adapted forfiltering rain-water collected from a roof prior to discharging the sameinto a cistern or storage-tank.

Another object of the invention is to effectually remove leaves andother trash from the water and to maintain the trash-separating screenfree from accumulations of foreign matter.

A still further object of' the invention is to provide for controllingthe flow of water through the filter, so as to direct the same to theoutlet leading to the cistern, and to run the water in another directionthrough the filter, so as to cleanse the filtering material and to carryofll the dirty water through a suitable drain.

Wvith these and other objects in view the present invention consists inthe combination and arrangement of' parts, as will be hereinafter morefully described, shown in the accompanying drawings, and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claims without departing from the spirit or sacrificing anyof' the advantages of the invention.

In the accompanying drawings, Figure 1 is a vertical longitudinalsectional View of a filter embodying the features of the presentinvention. Fig. 2 is a detail sectional view, taken through the valvemechanism, showing the same adjusted for cleansing and Vdraining thefilter.

Like characters of reference designate corresponding parts in bothigures of the drawings.

In carrying out the present invention there is provided a tank orreceptacle 1, having a removable cover 2, which is pierced by aninlet-pipe 3, designed for communication with a down-spout. At asuitable distance above the bottom of the tank or receptacle there is ascreen or perforate partition 4, and a similar screen or partition issupported in the upper portion of the tank upon suitable brackets 6. lnalinement with the inlet-pipe 3 there is a vertical pipe or passage 7,which pierces the two perforate partitions or screens 4 and 5, and atone side of this pipe there is another pi e 8, which also pierces thepartitions 4 an( 5. Suitable filtering material 9, such as charcoal orthe like, is placed in the tank 1 between the partitions 4 and 5 andaround the pipes 7 and 8.

The compartment 10 above the upper partition 5 is entirely free fromfiltering Inaterial and contains a hopper 11, arranged to receive theWater passing through the inletpipe 3 and having its bottom providedwith a short outlet-pipe 12, telescoped within the pipe 7, so as tosupport the hopper in position. A downwardly-inclined screen 13 isprovided across the top of the hopper, so as to exclude leaves and othertrash from passing downwardly through the pipe 7, said screen beinginclined downwardly to the outer end portion 14 of the hopper, whichprojects through an opening 15 in one side of the tank, said openingbeing large enough to permit of the escape of the trash which isseparated from the water by the inclined screen 13, which acts as achute to effectually discharge the trash from the filter.

For controlling the passage of the water through the filter avalve-chamber 16 in the nature ofl a cylinder is provided in the bottomportion of the tank. 1 below the partition el, with its opposite endsprojecting externally of the tank. One end 17 of this valve-chamber isopen, and its opposite end is closed by a cap 18, through which works avalve-stem 19, having a suitable handle 2O upon its outer end andprovided with spaced diskshaped valves 21 and 22, which normally occupythe positions shown in Fig. 1. Adjacent the drainterminal 17 of thevalvechamber and within the tank 1 said chamber is provided with anannular series of perforations 23, and adjacent the opposite end of thevalve-chamber there is an outlet-opening .24 in communication with apipe or passage 25, which leads to a cistern or storage-tank. (Not shownin the accompanying drawings.)

In practice, the valves being in the positions shown in Fig. 1, Waterentering the inlet-pipe 3 passes through the screen 13, which removesleaves and other trash, and the water IOO passes on down 'through thepipe 7 into the valve-chamber 16, thence outward through theperforations 23 into the bottom of the tank 1 beneath the partition 4.The water then rises through the perforate partition 4 and through thefiltering material until it reaches the upper compartment 10, whereuponit passes downwardly through the pipe or passage 8 into the rear endportion of the valve-chamber 16, and thence outwardly through the outlet25. After the device has been in use for some time and it is desired tocleanse the filtering material the valve-stem is pulled rearwardly tobring the valves in the positions shown in Fig, 2, whereupon waterentering the valve-chamber 16 through the pipe 7 rises through the pipe8 into the upper compartment 10, and thence passes downwardly throughthe filtering material into the bottom portion of the tank below thelower partition 4, and thence outward through the perforations 23 andthe open drain end 17 of the valve-chamber.

From the foregoing description it will be understood that leaves andother trash are always separated from the water in a simple andeflicient manner, such trash being automatically discharged from thefilter without requiring any manual handling thereof. Moreover, thewater may be caused to flow through the ltering material in a reversedirection to the normal direction of flow for the purpose of agitatingand stirring up the filtering material to loosen and carry 0H sedimentthrough a drain-opening, the'usual outlet for the iiltered water beingclosed to prevent fouling of the iiltered water in the cistern. y

Having thus described the invention, what is claimed 1s- 1. In a filter,the combination of av tank having a pair of perforate partitionsdividing the same into an intermediate and end compartments, theintermediate compartment eing adapted to contain a filtering medium, avalve-chamber within one of the end compartments and provided with adrain-outlet and an outlet for filtered water, an inlet-pipecommunicating with the other end compartment, a pipe communicating withthe inletpipe -and the valvechamber, another pipe communicating betweenthe valve-chamber and the opposite end compartment, a valve controllingthe ltered-water outlet and the second-mentioned pipe, and another valvecontrolling the drain-outlet.

2. In a iilter, the combination of a tank, a pair of perforatepartitions dividing the same into an intermediate and opposite endcompartments, the intermediate compartment being adapted to receive aiiltering element, a valve-chamber in one of the end compartments, aninlet-pipe leading into the other end compartment, a main pipecommunicating between the inlet-pipe and the valvechamber, a branch pipecommunicating between the valve-chamber and the opposite endcompartment, the valve-chamber being,

provided at one end with a filtered-water outlet and at its opposite endwith a drain-outlet there being an opening in the valve-chamber at theinner side of the drain-outlet to communicate with the adjacent endcompartment, a valve-stem working in the valvechamber, and spaced valvescarried by the stem, one of the valves being arranged for controllingthe opening which communicates with the valve-chamber and the adjacentend compartment and the other valve controlling the branch pipe and theltered-water outlet.

3. In a iilter, the combination of a tank having spaced perforatepartitions dividing the same into an intermediate compartment and upperand lower end compartments, the intermediate compartment being adaptedto contain a iiltering element, a valve-chamberwithin the lower endcompartment and provided with a drain-outlet and an outlet for thefiltered water, an inletpipe leading to the upper end compartment, ahopper contained within the upper end compartment to receive the waterfrom the inlet-pipe, an inclined screen carried by the hopper across thepath of the incoming water, the upper compartment of the tank having aside opening through which the lower end of the screen projects todischarge trash therethrough, a

main pipe leading from the hopper through the intermediate compartmentto the valvechamber, a branch pipe leading upwardly from thevalve-chamber to the upper compartment, the valve-chamber being providedwith an opening communicating with the adjacent end compartment adjacentthe drainoutlet, a valve working in the valve-chamberA and controllingthe said opening, and another valve working in the valve-chamber andcontrolling the branch pipe and the outlet for filtered water.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in the presence of two witnesses.
